Research on Chaotic Dynamical Characters of EEG Model
Zhao Haibin · Jisuanji fangzhen · 2010
EEG is the expression of brain electrophysiological activity in macroscopic scales,and the rule of brain activity can be recognized by analyzing nonlinear dynamics of EEG model.Regarding the excitatory inputs to excitatory populations as a parameter,correlation dimension and largest Lyapunov exponent were calculated.Numerical simulation shows complex dynamical behaviors,such as limit cycle,doubling-period bifurcation,chaos and so on,provide the evidence that chaos exists in EEG model.
